Description

Technical Field

[0001] The present application relates to the technical field of irradiation devices for solar cells, and in particular to an irradiation device for solar cells. Background Art

[0002] In order to ensure the working efficiency of solar panels, the cells need to be tested during the processing process to ensure that they have good electrical performance parameters.

[0003] As part of the testing device, the xenon lamp has a wide spectrum range, high brightness and good stability, and is widely used in IV testing.

[0004] In current technology, the xenon lamps of some test equipment are horizontally mounted at the rear of the light guide cavity. When replacing a xenon lamp, the lamp needs to be pulled out horizontally. Xenon lamps are generally over 1.2 meters long, and some laboratories have limited width. If the xenon lamp is fully extended, the width of the laboratory will not be sufficient. Therefore, when replacing a xenon lamp, when one end of the xenon lamp touches the wall, the xenon lamp may not be fully extended. In this case, the xenon lamp needs to be tilted at a certain angle to fully extend. This makes the installation and maintenance process very inconvenient when replacing the xenon lamp.
